On-board data acquisition systems KiHUB for crash testing applications / K3879B

The KiHUB represents an intelligent terminal block that combines the different Kistler data acquisition systems concerning communication, power, and trigger distribution. The power supply of KiHUB is provided via the trailing cable (CrashLink2) plug-in point (range 20 … 60 V) or the CrashLink1 (range 20 … 36 V) connection. By default, both plug-in points are decoupled internally by a diode in order to avoid unintended electrical surges on the CrashLink1 interface. Furthermore, KiHUB is equipped with a battery for at least 240 seconds. This secures Ethernet communication and trigger event distribution in the case of power breakdown during a test. This time is changeable through an internal DIP switch.
